For centuries, the nation-state of Szo have primarily fed their people with domestic szon and, in turn, fed their szon with their recently-deceased citizens. As a result, this domesticated variant of the deep-sea szon has taken on a deep symbolism for responsible population control. The domestic szon lacks the large mouth of its oceanic cousin and instead absorbs food particles through its gills, where it's filtered into the stomach. In times of crisis, Szo has been able to economically recover almost entirely from exports of an overabundance of szon.
